The demos call SDLEvent.enableUNICODE(1) explicitly, and the text input 
fields and areas are working there, so I assume that it is the right 
thing to do.  I didn't have much time to work on the game for which I 
ported guichan originally so I don't have too much experience with it 
either (ironically :)).
